Surprise! Asteroid Hosts A Two-Ring Circus Above Its Surface
{"Image ImageDescription": "Observations at many sites in South America, including ESO\u2019s La Silla Observatory, have made the surprise discovery that the remote asteroid Chariklo is surrounded by two dense and narrow rings. This is the smallest object by far found to have rings and only the fifth body in the Solar System \u2014 after the much larger planets Jupiter, Saturn, Uranus and Neptune \u2014 to have this feature. The origin of these rings remains a mystery, but they may be the result of a collision that created a disc of debris. This artist\u2019s impression shows how the rings might look from close to the surface of Chariklo."}
